• hello,

    The join between #source and #Target in the SELECT .... EXCEPT is not essential

    You can obtain the same result with a best cost

    SELECT .[ID]

    , .[Item]

    , .[Price]

    , .[OrderDate]

    , .[Units]

    , .[ShipmentDate]

    FROM [Source]

    EXCEPT

    SELECT [T].[ID]

    , [T].[Item]

    , [T].[Price]

    , [T].[OrderDate]

    , [T].[Units]

    , [T].[ShipmentDate]

    FROM [Target] [T]

    ;

    Am I wrong?

    Arnaud
